Interface GeodesicReconstructionAlgo

All Known Implementing Classes:

GeodesicReconstructionAlgoStub, GeodesicReconstructionByDilation, GeodesicReconstructionByErosion, GeodesicReconstructionHybrid, GeodesicReconstructionScanning

public interface GeodesicReconstructionAlgo

Defines the interface for geodesic reconstructions algorithms applied to planar images.

There are currently four implementation of geodesic reconstruction for planar images:

• GeodesicReconstructionByDilation: implements reconstruction by dilation, using scanning algorithm
• GeodesicReconstructionByErosion: implements reconstruction by erosion, using scanning algorithm
• GeodesicReconstructionScanning: implements reconstruction by dilation or erosion, using scanning algorithm.
• GeodesicReconstructionHybrid: implements reconstruction by dilation or erosion, using a classical forward pass, a backward pass that initialize a processing queue, and processes each pixel in the queue until it is empty.

The most versatile one is the "Hybrid" version.

Method Detail

applyTo

ij.process.ImageProcessor applyTo(ij.process.ImageProcessor marker,
                                  ij.process.ImageProcessor mask)

Applies the geodesic reconstruction algorithm to the input marker and mask images.

Parameters:

marker - image used to initialize the reconstruction

mask - image used to constrain the reconstruction

Returns:

the geodesic reconstruction of marker image constrained by mask image

getConnectivity

int getConnectivity()

Returns the chosen connectivity of the algorithm, either 4 or 8.

Returns:

the current connectivity for this algorithm

setConnectivity

void setConnectivity(int conn)

Changes the connectivity of the algorithm to either 4 or 8.

Parameters:

conn - the connectivity to use, either 4 or 8
